Create or review Blazor components, reusable parts of a web interface. Covers passing data and events between parent and child components, content templates, asynchronous work, display states, and resource cleanup when components are removed.

Create or review Blazor components (.razor files) with correct architecture. USE FOR: writing new Blazor components that do NOT involve JavaScript interop, implementing parameters and EventCallback, RenderFragment slots, component lifecycle (OnInitializedAsync, OnParametersSet), async patterns, IAsyncDisposable, CancellationToken, CSS isolation, code-behind. DO NOT USE FOR: creating new projects (use create-blazor-project), JavaScript interop or calling browser APIs from Blazor (use use-js-interop), forms and validation (use collect-user-input), prerendering issues (use support-prerendering), HTTP data fetching patterns (use fetch-and-send-data), coordinating state between unrelated components (use coordinate-components).

[Parameter]. Events flow up via EventCallback<T> (never Action/Func).[Parameter] properties. Copy to a private field in OnParametersSet.[Parameter] public T Prop { get; set; } — never required or init (causes BL0007).[EditorRequired] for required parameters.@if/@else.@key on repeated elements in loops for efficient diffing.IReadOnlyList<T> (not IEnumerable<T>) for collection parameters.[Parameter] public RenderFragment? ChildContent { get; set; }
[Parameter] public RenderFragment<TItem>? RowTemplate { get; set; } // generic template
Use @typeparam TItem for generic components.
.razor with @code block when logic < ~50 lines..razor + .razor.cs with partial class when logic > ~50 lines.Implement IAsyncDisposable (not IDisposable) when the component owns subscriptions, timers, or CTS.
In DisposeAsync: unsubscribe (-=), cancel CTS, dispose resources. Never call StateHasChanged.
await every async operation. Never use .Result, .Wait(), Task.Run, ContinueWith, Thread.Start.Task.Delay + CancellationTokenSource. Cancel old CTS, create new, await delay, do work. Never use System.Threading.Timer or System.Timers.Timer.OnInitializedAsync with await Task.Delay(interval, token) — stays on sync context.Action<T>): Use async void handler + await InvokeAsync(() => { state++; StateHasChanged(); }) + catch → DispatchExceptionAsync. Never _ = InvokeAsync(...).DisposeAsync. Don't catch ObjectDisposedException — use CTS cancellation.required/init on [Parameter] — runtime failure[Parameter] — copy to private field in OnParametersSetAction/Func for events — use EventCallback<T>Task.Run/.Result/.Wait()/Timer for debounce — deadlock or thread-pool escapestyle attributes — use CSS classes or data-* attributescatch { throw; } — use when guard or let exceptions propagate_ = InvokeAsync(...) — swallows exceptions; use async void + DispatchExceptionAsync还没有评价。欢迎分享你的使用感受。
